I guess it depends what you mean by outdid? If you mean more popular then open source web frameworks are wildly more popular than the equivalent closed source ones (ignoring ecommerce for the time being). If you mean technically better then you’d be hard pushed to argue that the Windows kernel is much better than the Linux kernel. If you mean genuinely a better user experience, then Firefox vs Internet Explorer comes to mind.
